Business hours: Everyday, 24 hours
Founded by an ex-Army officer, Security Risk Specialists (SRS) doesn’t just offer a generic fix for every client. They assess risks and create a tailored security plan.

Their team is well-trained, regularly updated on counterterrorism intelligence, and always prepared for emerging risks. Not to mention that clients love their dedication and professionalism, especially when securing high-profile events.
However, some customers have expressed frustration with poor customer service, particularly when calling their support line because certain staff members can be unhelpful or lack professionalism.
Concerns have also been raised about SRS’s effectiveness in certain situations, such as a property displaying their security signs but still being taken over by squatters. While no security company can guarantee 100% prevention, incidents like this can raise doubts.

They used to impress all staff and visitors with their professionalism and dedication. The guards were not only skilled and experienced in their duties but also proactive in ensuring the safety and security of all staff and the premises. They were always approachable and willing to help with any queries, which created a welcoming environment for everyone in the office… SRS consistently worked to understand our specific security needs and preferences and provided tailored services accordingly. They ensured that our office environment remained secure without feeling overly guarded or restricted.”
